You get a water hammer when you shut off the flow, not when you open it.
Firing a piece of munition that is worth many times the target is a win for the enemy even if you hit it, they can just keep lobbing Ali Express crap at you until you run out of missiles.
Donald Trump is definitely a person who doesn't get mentioned enough here.
The pager attack was, from a technical point of view, an incredible feat. I do see how you'd find some of the jokes in poor taste though.
Why does Mary have a full face of makeup and look a rough early forties?
People make jokes about Musk fanboys, but some of the haters are absolutely deranged.
That's not the comment that was taken down though.
That's to test the incoming main, the actual grid on the floor doesn't get flushed. There's a lot of dead end pipes that can't be flushed.
Yes. A combination of rust, thread cutting oil, and water that has been in the pipes often since the system was filled. It smells, it will stain anything it touches, and it's a smell that's difficult to remove.
This happens with fire sprinklers a lot, one sprinkler goes off, and triggers the rest of the floor, or sometimes even building.
That's not how it works. Each sprinkler has it's own trigger mechanism, the glass bulb, and cannot trigger another sprinkler.
There are systems where this happens, but the sprinkler heads look very different, and you won't find them in an office building.
There's something that people really fail to grasp with solar, and that's the fact there is bugger all energy in the sun, and you need a huge surface area to get any meaningful energy.
A home solar array often takes up a significant chunk of the roof area, and the amount of surface area a car typically has means that even perfectly efficient solar panels wouldn't collect enough energy to significantly contribute to the vehicle's range.
There's a good reason why vehicle manufacturers don't bother adding them.
It definitely is.
It has a particular smell that doesn't come out of fabric easily, either.
